Objective To compare the incidence of complications after removal of chest drainage tube in the early and late stages after sublobectomy for non-small cell lung cancer (NSCLC), and to analyze the factors affecting postoperative pleural drainage volume (PDV), so as to explore the countermeasures and achieve rapid postoperative rehabilitation. Methods The patients with NSCLC who underwent minimally invasive sublobectomy in our hospital from January to October 2021 were enrolled. According to the median time of extubation, the patients were divided into an early extubation group (time with tube≤3 days) and a late extubation group (time with tube>3 days). The patients were matched via propensity score matching with a ratio of 1:1 and a caliper value of 0.02. The incidence of complications and perioperative parameters after removal of the thoracic drainage tube were analyzed and compared between the two groups, and univariate and multiple linear regression analyses were performed. Results A total of 157 patients were enrolled, including 79 males and 78 females, with an average age of (58.22±11.06) years. There were 76 patients in the early extubation group, 81 patients in the late extubation group, and 56 patients were in each group after propensity score matching. Compared with late extubation group, there was no significant difference in the incidence of infection after extubation (10.7% vs. 16.1%, P=0.405) or pleural effusion after extubation (5.4% vs. 3.6%, P=0.647) in early extubation group, and there was no second operation in both groups. Univariate analysis showed that smoking history (P=0.001), postoperative serum albumin reduction value (P=0.017), surgical approach (P=0.014), lesion location (P=0.027), differentiation degree (P=0.041), TNM stage (P=0.043), number of dissected lymph nodes (P=0.016), and intraoperative blood loss (P=0.016) were infuencing factors for increased postoperative PDV. Multiple linear regression analysis showed that smoking history (P=0.002), postoperative serum albumin reduction value (P=0.041), and the number of dissected lymph nodes (P=0.023) were independent risk factors for increased postoperative PDV. Conclusion There is no significant difference in the incidence of complications after extubation between early and late extubations. Preoperative smoking history, excessive postoperative serum albumin decreases, and excessive number of dissected lymph nodes during the surgery are independent risk factors for increased postoperative PDV.

Objective To investigate the safety and efficacy of totally no tube three-port thoracoscopic surgery (TNTT) for thymic tumor via lateral thoracic approach. Methods The clinical data of patients with thymoma admitted to the Department of Thoracic Surgery of the General Hospital of Northern Theater Command from November 2021 to May 2022 were retrospectively analyzed. The patients were divided into a TNTT group and a single utility port video-assisted thoracic surgery (SVATS) group according to different surgical methods. The clinical data were compared between the two groups. Results A total of 111 patients were collected. There were 44 patients in the TNTT group, including 20 males and 24 females, with an average age of 60.11±8.64 years, and 67 patients in the SVATS group, including 30 males and 37 females, with an average age of 62.40±7.92 years. There was no significant difference between the two groups in the baseline data (P>0.05). The postoperative hospital stay and intraoperative blood loss were shorter or less in the TNTT group (P<0.05), and the visual analogue scale score 48 hours after the operation was smaller in the SVATS group (P<0.05). Conclusion TNTT has a good surgical safety, and can shorten postoperative hospital stay, reduce intraoperative blood loss, and has significant advantages in enhanced recovery after surgery, but SVATS can reduce postoperative pain in patients.

Objective:To explore the application effect of group guidance based on intelligent communication matrix in patients with type 2 diabetes mellitus (T2DM) .Methods:Using the convenient sampling method, a total of 60 T2DM patients with poor self-management ability who scored less than 19.6 on Summary of Diabetes Self Care Activities (SDSCA) in the Affiliated Chuzhou Hospital of Anhui Medical University were selected as the research objects from May to June 2020. They were randomly divide into the observation group ( n=30) and the control group ( n=30). The observation group was given continuous group guidance based on intelligent communication matrix, while the control group was given routine health guidance. The SDSCA score, body mass index and glycosylated hemoglobin (HbA1c) before and after intervention were compared between the two groups. Results:After intervention, the SDSCA score of the observation group was higher than that of the control group, HbA1c was lower than that of the control group and body mass index was lower than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The group guidance based on intelligent communication matrix can improve the self-management level of T2DM patients and reduce their body mass index and HbA1c levels, which has clinical application value.

Objective To investigate sex-related differences in left ventricular systolic dysfunction in heart failure with preserved ejection fraction(HFpEF)and type 2 diabetes mellitus(T2DM).Methods A total of 228 HFpEF patients who were treated in the Department of Endocrinology and Cardiology of the Second Hospital of Shijiazhuang from January 2019 to June 2023 were enrolled.They were divided into HFpEF group[women(n=61),men(n=73)]and HFpEF+T2DM group[women(n=49),men(n=73)]according to whether they had T2DM.Conventional echocardiography and left ventricular global longitudinal strain(GLS)data were measured.Sex-related differences of left ventricular structure and function were compared between the two groups.Multivariable linear regression analysis was performed for the determinants of impaired left ventricular GLS for HFpEF with T2DM patients and HFpEF patients of both sexes.Results LVMI was lower in women than in men in HFpEF group(P<0.05).The left ventricular remodeling rate of women was higher in HFpEF+T2DM group than that of men and women in HFpEF group,and the GLS of women was lower than that of men and women in HFpEF group(P<0.05).The E/E'was higher in women than in men in HFpEF and HFpEF+T2DM groups(P<0.05).Multivariable linear regression analysis showed that age,women,HbA1c and LVMI were the determinants of GLS impairement in HFpEF patients with T2DM.Age,T2DM,NT-proBNP and LVMI were the determinants of GLS impairement in HFpEF women patients,where as age,BMI,CHD,NT-proBNP and LVMI were the determinants of GLS impairement in HFpEF men patients.Conclusions There are sex-related differences in left ventricular systolic dyfunction in HFpEF with T2DM patients.With T2DM exerting a greater adverse effect onleft ventricular systolic dyfunction in women with HFpEF than men.

Objective:To systematically review the research hotspots and trends in the diagnosis and treatment of depressive disorder in general practice over the past 20 years.Methods:Relevant Chinese and English literature was retrieved from CNKI and the Web of Science Core Collection using search terms "general practice" "depression" "general practi*" and "depress*". The search period was from January 1, 2003, to December 31, 2022. Citespace 6.2R2 advanced edition software was used to perform a visual analysis of the annual publication volume, research institutions, authors, keywords, burst terms, and time zone map of the included literature.Results:A total of 169 Chinese and 231 English literatures were included. Over the past two decades, the number of literatures in China has grown rapidly, while overseas literatures have remained stable. Domestically, collaborations between research institutions were mainly concentrated within the same region, particularly around primary care centers and specialty hospitals in Shanghai. International collaborations were relatively more dispersed, mainly around higher education institutions and university-affiliated general hospitals in Europe and Australia, showing a more diverse form of collaboration. Keyword cluster analysis showed that domestic studies focused mainly on 11 topics such as "depression""anxiety" and "health status", while foreign studies identified 11 topics including "chronic diseases""mortality" and "depressive disorders". Keyword time zone analysis showed that previous research topics, such as the prevalence of depressive symptoms and their influencing factors, depression and quality of life in the elderly, have recently shifted to include the detection rate of mental disorders in general outpatient practice, as well as an evaluation of the role of family doctors and general care in comorbid and chronic disease management.Conclusions:Domestic research on the diagnosis and treatment of depressive disorders in general practice is increasing. The focus and frontiers of domestic and foreign research are mainly focused on the effectiveness and accuracy of screening for depressive disorder, and mental health intervention and whole-cycle management for patients diagnosed with depression.

Objective To construct a rapid prediction system to improve the accuracy and efficiency of evaluation of the consequences of nuclear accidents at a field scale. Methods Base on a diagnostic wind field model and Lagrangian particle diffusion, we established a rapid prediction method for wind field and pollutant dispersion around complex underlying surfaces within a field scale, in a way of visual discrimination of buildings and vegetation distribution. With data simulation and the use of a real urban field example, the simulated results were compared with wind tunnel test measurements and computational fluid dynamics results to study the influence of complex underlying surfaces on wind field and pollutant transport in the region. Results The rapid prediction system could clearly simulate the high-resolution wind field and pollutant concentration distribution of the region in about five minutes. It could interface with geographic information software and couple with a mesoscale weather prediction model. In terms of accuracy, the system performed well in wind field simulation, with the fractional deviations of wind speed and wind direction being 0.33 and −0.08, respectively. Concentration field simulation was greatly affected by the wind field, and the ratios of simulated concentrations to observed concentrations were between 0.05 and 3.4, except for a few low concentration points. Conclusion The rapid prediction system can effectively simulate the distribution characteristics of the flow field and improve calculation efficiency when ensuring calculation accuracy, which provides an important reference for emergency response to nuclear accidents.

Objective:To document any effect of environmental enrichment on nerve regeneration in a mouse model of sciatic nerve compression and explore its mechanism.Methods:A crushed sciatic nerve model was successfully established in 22 C57BL/6 mice, and they were then randomly divided into an intervention group and a control group. The mice of the intervention group were raised in a cage with an enriched environment, while those of the control group were kept in a standard cage. Two weeks later, both groups′ gait was analyzed and the compound muscle action potential (CMAP) of the sciatic nerve was measured. The proportion of myelinated sciatic nerve fibers was examined using toluidine blue staining, and the expression of myelin basic protein (MBP), growth associated protein-43 (GAP43) and p75 neurotrophin receptor (p75 NTR) was measured using immunofluorescence intensity. Results:①The latency of the CMAP [(1.05±0.04)ms] was significantly shortened in the intervention group compared with the control group and the amplitude was significantly higher. ②Gait analysis showed a significant increase in the average contact intensity, stride length and stride rate of the intervention group compared with the control group. However, the step axis angle of the intervention group was significantly smaller than in the control group on average. ③The stained nerve fibers in the intervention group were orderly and dense, and the average number of myelinated fibers was significantly greater than in the control group. ④Quantitative analysis of the immunofluorescence showed that the levels of MBP, GAP43 and p75 NTR in the sciatic nerves of the intervention group were, on average, significantly higher than in the control group. Conclusion:An enriched environmental can promote the regeneration and functional recovery of crushed sciatic nerves by promoting the proliferation and myelination of Schwann cells.

Objective     To compare the clinical efficacy and safety of da Vinci robot with totally no tube (TNT) versus subxiphoid video-assisted thymectomy surgery (SVATS) in the treatment of thymic tumors. Methods     From 2019 to 2021, a retrospective analysis was conducted on patients with thymic tumor resection in the Department of Thoracic Surgery, General Hospital of Northern Theater Command. All patients underwent total thymectomy and mediastinal fat removal, and they were divided into a TNT group and a SVATS group according to the operation method. The intraoperative blood loss, conversion rate, postoperative visual analogue score (VAS), postoperative hospital stay time and postoperative complications were compared between the two groups. Results     We finally included 435 patiets. There were 168 patients with 83 males and 85 females at an average age of 61.920±9.210 years in the TNT group and 267 patients with 147 males and 120 females at an average age of 61.460±8.119 years in the SVATS group. There was no death or postoperative myasthenic crisis in both groups. There was no statistical difference in postoperative hospital stay (1.540±0.500 d vs. 3.400±0.561 d, P=0.000), intraoperative blood loss (13.450±5.498 mL vs. 108.610±54.462 mL, P=0.000), postoperative 24 h VAS score (4.960±1.757 points vs. 3.600±1.708 points, P=0.000), or postoperative complication rate (3.0% vs. 11.6%, P=0.001). Conclusion     TNT is a more efficient, safe, and effective surgical approach for treating thymic tumors, which can shorten hospital stay time and reduce postoperative complications. However, SVATS can minimize postoperative pain.

Objective:To explore the expression of long-chain noncoding RNA (lncRNA) and myocardial infarction-associated transcription (MIAT) in Leukocyte differentiation antigen (CD)4+T cells in peripheral blood of gastric cancer patients and its value of clinical application.Methods:Peripheral blood CD4+T cells were collected from 124 patients with gastric cancer, 90 benign gastric diseases patients and 80 healthy controls enrolled in Taizhou People′s Hospital from January 2019 to April 2021. The expression levels of MIAT and N6-methyladenosine(m6A) binding to MIAT promoter in CD4+T cells were detected by real-time fluorescent quantitative polymerase chain reaction (qPCR) and Chromatin immunoprecipitation (ChIP)-qPCR, respectively. Spearman test was used to analyze the correlation between MIAT and clinicopathological features, as well as between MIAT and regulatory T cell levels. The receivor operating characteristic curve (ROC) of the subjects was used to evaluate the MIAT expression level in the auxiliary diagnostic value of gastric cancer.Results:The relative expression levels of MIAT in the gastric cancer patients, the benign gastric diseases patients, and the healthy controls were 2.849 (2.131, 4.062), 1.511 (0.916, 1.855) and 0.963 (0.729, 1.432), respectively. The difference among the three groups was statistically significant ( H=158.25, P<0.001). The relative expression level of MIAT in the gastric cancer patients was significantly higher than the levels in the benign gastric diseases patients and healthy controls. The difference was statistically significant ( Z=100.63, 145.14, P<0.001). The binding activity of m6A to MIAT promoter in patients with early stage (stage Ⅰ and Ⅱ) and end stage (stage Ⅲ and Ⅳ) gastric cancer was 8.590±1.483 and 4.274±0.425, respectively. The difference was statistically significant ( t=6.255, P=0.002). Furthermore, the binding activity of m6A to MIAT promoter in the gastric cancer patients was significantly lower than that in patients with benign gastric diseases (17.267±3.106) and healthy controls (27.637±3.945) ( t=-7.331,-12.832, P<0.001). The relative expression of MIAT in CD4+T cells in peripheral blood of the gastric cancer patients had no significant difference in age(χ2=0.000, P=1.000), gender(χ2=0.000, P=1.000), CEA (χ2=0.648, P=0.421) and CA199(χ2=1.554, P=0.213), but had significant difference with tumor size expression(χ2=9.443, P<0.01), TNM stage(χ2=23.571, P=0.002) and lymph node metastasis (χ2=45.248, P<0.01). In addition, there was a significant positive correlation between the relative expression of MIAT in CD4+T cells and Treg level ( r2=0.76, P<0.001). The diagnostic efficacies of MIAT in CD4+T cells, CEA and CA199 in the gastric cancer patients were analyzed by ROC curve. When compared with patients with benign gastric diseases, the areas under the curve were 0.879, 0.635 and 0.611, respectively. When compared with healthy patients, the areas under the curve were 0.953, 0.784 and 0.598, respectively. Conclusions:The level of MIAT in CD4+T cells in peripheral blood of patients with gastric cancer is significantly higher than the levels in patients with benign gastric diseases and the healthy controls, which may be related with the decreased activity of m6A binding to the promoter of MIAT. The level of MIAT in CD4+T cells may be a relevant biomarker for the diagnosis and prognosis of gastric cancer.
